Transmit Data Positive: 100Base-TX or 10Base-T differential
transmit outputs to magnetics.
Transmit Data Negative: 100Base-TX or 10Base-T differential
transmit outputs to magnetics.
Receive Data Positive: 100Base-TX or 10Base-T differential
receive inputs from magnetics.
Receive Data Negative: 100Base-TX or 10Base-T differential
receive inputs from magnetics.
Connects to reference resistor of value 12.4K-Ohm, 1%
connected as described in the Analog Layout Guidelines. The
nominal voltage is 1.2V and therefore the resistor will dissipate
approximately 1mW of power.
+1.6V to +3.6V Variable I/O Pad Power
+3.3V Core Regulator Input.
+3.3V Analog Power
+1.8V (Core voltage) - 1.8V for digital circuitry on chip. Supplied
by the on-chip regulator unless configured for regulator off
mode using the RX_CLK/REGOFF pin. Place a 0.1uF capacitor
near this pin and connect the capacitor from this pin to ground.
When using the on-chip regulator, place a 4.7uF ±20%
capacitor with ESR < 1ohm near this pin and connect the
capacitor from this pin to ground. X5R or X7R ceramic
capacitors are recommended since they exhibit an ESR lower
than 0.1ohm at frequencies greater than 10kHz.
Exposed Ground Flag. The flag must be connected to the
ground plane with an array of vias as described in the Analog
Layout Guidelines
